Abstract

PURPOSE:To obtain an easy-to-assemble thin-type head by fitting to a housing a terminal member in a sheet-like shape having a conductor circuit for jointing electrically a magnetic recording device to a recording/reproducing coil and an erasing coil of a pushbutton-type magnetic head. CONSTITUTION:The terminal member 11 is prepared which provides a circuit on a sheet-like or plate-like base 8 with the use of a metallic foil 9 such as Cu. The member 11 is stuck to the rear side of the housing 4 for the pushbutton- type magnetic head, then the terminals of the recording/reproducing coil 5 and the erasing coil 6 are soldered on one end of the metallic foil 9. A cable 12, etc., are soldered on the other end of the foil 9 and connected to the recording device. Thus the thinning of the head can be facilitated and the head with the improved assembly workability can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic head, and more particularly to a fixed magnetic head for a floppy disk drive that performs digital magnetic recording.

Conventional technology The magnetic head for floppy disks is a fixed head (
button type), semi-fixed head (gimbal type),
Broadly divided into movable heads.

FIGS. 4(a) and 4(b) are perspective views of a conventional fixed head (button type).

This magnetic head consists of a recording/reproducing core 1, an erasing core 2 placed on both sides of the core, and sliders 3a and 3b placed on either side of the core, which are bonded together using glass, resin, etc. is inserted into the housing 4, fixed and held. A recording/reproducing coil 5 and an erasing coil 6 are inserted into the recording/reproducing core 1 and the erasing core 2, respectively, and the ends of the wound coils are connected to the housing 4.
It is coupled to a plurality of terminal pins 7 inserted into the back surface of the terminal.

Problems to be Solved by the Invention However, in the conventional magnetic head having the above structure, since a plurality of terminal pins 7 are inserted in the height direction of the housing 4, it is difficult to reduce the height of the magnetic head. This is a factor that prevents recording devices from becoming thinner. Further, when connecting the magnetic head, a plurality of terminal pins 7 must be inserted into the housing 4, and the assembly work is complicated.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks, provide a magnetic head that is easy to assemble, and is suitable for thinning a recording device.

Means for Solving the Problems In order to achieve the above object, the present invention provides a recording/reproducing coil that generates magnetic flux in a recording/reproducing core and generates an induced voltage due to changes in the magnetic flux, and a magnetic flux in an erasing core. A sheet-like or plate-like terminal member having a dielectric circuit for electrically coupling the recording/reproducing coil and the erasing coil to a magnetic recording device. is attached to the housing.

Function: Since the terminal member is formed in a sheet or plate shape, the height of the housing does not increase significantly when it is attached to the housing, and therefore the device can be made thinner. can be achieved. Also,
Since a plurality of conventional terminal bins can be assembled into the terminal member using the conductor, the assembly work can be facilitated.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 2 shows a terminal member 11 in which a circuit is formed on a sheet-like base 8 using copper foil 9 as a conductor. Instead of the copper foil 9, aluminum foil can also be used. Also,
In consideration of workability, an adhesive is attached to the back surface of the base 8.

FIG. 3 shows another example of the terminal member 11, in which a base 8 is bonded onto a glass epoxy plate 10 to provide strength.

FIG. 1 is a diagram showing a magnetic head using the film-like terminal member 11 shown in FIG. 2. As shown in FIG.

Attach the terminal member 11 to the back side of the housing 4,
The terminals of the recording/reproducing coil 5 and erasing coil 6 are soldered to one end of the copper foil 9 on the terminal member 11. Further, a cable 12 or the like is soldered to the other end of the copper foil 9 and connected to the recording device.

In this embodiment, the terminal member 11 is thin in the height direction of the housing 4, and there is no need to insert it in the height direction unlike a conventional terminal bin, so that the height of the magnetic head can be reduced.
1') can be designed to be thin, making it easy to make the recording device thinner. Furthermore, since a plurality of terminal bins are assembled in one terminal member 11, the assembly work efficiency can be significantly improved.

Effects of the Invention As described above, according to the present invention, since the terminal member is formed in a sheet or plate shape, the height of the housing does not increase significantly when attached to the housing. The device can be made thinner. Furthermore, since a plurality of conventional terminal bins can be assembled into the terminal member using the conductor, the assembly work can be facilitated.
